In this case, the control section may display UF (underflow) on the weight display section 13. In other words, since the weight cannot be displayed, a symbol is displayed instead of the value. On the other hand, if the weight value exceeds the weighed value, a weight overflow (OF) occurs.

The product selection button display area 23 displays the product selection button 28 selected by operating the product information display device 51. In other words, the product selection button display area 23 displays only the product selection buttons selected on the product information display device 51. The operator operating the weighing device 1 operates the product selection button 28 in the product selection button display area 23 to specify the product to be weighed with the weighing device 1 and weigh the product. Note that when a plurality of different product information display devices 51 are operated, a plurality of products are displayed as product selection buttons 28 in the product selection button display area 23. In addition, when the product information display device 51 is operated multiple times, it is determined how many times the same product has been operated (multiple touches), and the product corresponding to the product information display device 51 is displayed in the product selection button display area 23. The number of times the selection button 28 is operated (touched) is displayed as a number on the product selection button 28.
In addition, when a mobile terminal device such as a smartphone and the weighing device 1 are mutually connected, the mobile terminal device such as a smartphone may be used to display electronic shelf labels, etc. (or POP advertisements using paper media, etc.). ) out of the information displayed on the screen, the code information, etc. is imaged by an imaging means (camera, etc.) included in a mobile terminal device such as a smartphone, and information that identifies the product from the image containing the captured code information (product ID or product identification). Information) may be extracted and stored, and when connected to the weighing device 1, the information identifying the stored product (product ID or product identification information) may be transmitted to the weighing device 1.
In this case, the weighing device 1 may display the product selection button 28 in the product selection button display area 23 based on the received information specifying the product (product ID or product identification information). In this case, a product selection button 28 will be displayed in the product selection button display area 23 according to the product (item) stored in a mobile terminal device such as a smartphone. Note that the control unit of the weighing device 1 receives product identifying information (product ID or product identification information) received from the product information display device 51, or product identifying information received from a mobile terminal device such as a smartphone.

The third display area 31 displays only selectable operation buttons 32 necessary for operating the weighing device 1 in the current state of the weighing device 1. In other words, the third display area 31 does not display (hides) buttons that are unnecessary for the current operation of the weighing device 1. Therefore, the operator who operates the weighing device 1 can operate the weighing device 1 intuitively.
Note that the third display area 31 shown in FIGS. 7 and 8 displays two operation buttons 32 (320a), a menu button and a prepack button, when the mode is different. The display of selectable operation buttons 32 necessary for operation is changed by varying the number and function of the operation buttons 32 to be displayed according to the type and number of payments. For example, the prepack button (operation button 320a) is a button for moving to a prepack screen 120, which will be described later. In addition, in the third display area 31, buttons for discounting or discounting the product are displayed while weighing the product or inputting the quantity, and buttons for payment selection, subtotal discount, and subtotal discount are displayed on the sub-plan screen. be done. Since unnecessary buttons are not displayed on the operation screen, operational errors are prevented and the operator is no longer confused about button selection.

When a store clerk's ID card 58 is detected by the sensor 10 or the communication unit of the weighing device 1, the fourth display area 41 displays information for identifying the store clerk such as the name and clerk ID of the clerk on the detected ID card 58 (the clerk's ID card 58). Store clerk information such as name, clerk ID, etc.) are displayed.
Specifically, when the sensor 10 or the communication unit of the weighing device 1 detects the store clerk's ID card 58, the fourth display area 41 of the store clerk display operation section 6 changes from the initial screen shown in FIG. 7 to the screen shown in FIG. 9(a). As shown in , a clerk button 42 indicating that a clerk has been detected is displayed. In addition, when the sensor of the weighing device 1 detects a plurality of clerks, the fourth display area 41 of the store clerk display operation section 6 displays a plurality of store clerk buttons 42 as shown in FIG. 9(b). is displayed in the fourth display area 41. When one of the plurality of clerks operates the weighing device 1, that clerk can operate the weighing device 1 after selecting the clerk button 42 indicating the clerk. In other words, when the sensor 10 detects a store clerk, the store clerk becomes able to operate the weighing device 1. That is, there is no need to provide a login button on the store clerk display/operation section 6 for the store clerk to operate the weighing device 1. Note that the weighing device 1 recognizes the store clerk who reached the range where the store clerk's ID card can be detected first, that is, the login order. Therefore, the product registration list screen of the store clerk who logged in first is displayed in the second display area and becomes operable. The second or subsequent store clerk who logs in presses the store clerk button 42 expressing confidence, thereby switching the second display area to a list screen of his/her own product registration. When the store clerk's ID code leaves the detection range, the screen automatically switches to the product registration list screen for the next logged-in store clerk, and when the store clerk leaves the detection range, the product registration list screen in the second display area is also hidden. becomes. If there is no product registered by the clerk, operational guidance such as "Please select a product" is displayed.
In other words, if there are no registered products in the login order, "Please select a product (select from the product selection button)", "Please specify a product (press the product information display device)", and if there are registered products, register Display a list of products. When a store clerk leaves the detection range, a list of registered products of the store clerk who is in the detection range and logs in first is displayed. When changing the store clerk to be operated, control is performed such that the change is made by touching the identification button of the store clerk.
The clerk button 42 also has the function of completing product registration. For example, each time a product to be purchased by a customer is registered in the weighing device 1 and the clerk button 42 is touched (pressed), the amount is added to the clerk button 42 . Note that adding a product to the clerk button 42 means that the product purchased by the customer is added as a product detail in one transaction. This function is to allocate a customer's transactions to a store clerk. As a result, even if the clerk operating the weighing device 1 is switched to another clerk, products purchased by different customers can be registered alternately by switching the clerk who can currently operate the store clerk button 42. In addition, if there is a customer who is having trouble selecting a product, the customer who is being handled by another store clerk can freely register the product to be purchased. As a result, even if there is only one weighing device 1, it is possible to handle a plurality of customers efficiently, smoothly and easily, which is economical and effective.
Furthermore, if multiple weighing devices 1 are connected (chain-connected) so that each data can be shared, store clerks and customers can be connected even in large sales areas, and store clerks can move with customers and sell a variety of products. It also has the effect of being able to

In addition, the first display area 11, second display area 21, third display area 31, and fourth display area 41, which are a plurality of display areas of the display operation section 6 for store clerks, have different display contents and number of items in each area. The size of each display area may be changed accordingly. For example, if the product to be weighed in one transaction is one product, the display area of the history display area 22 and product selection button display area 23, which are the second display area 21, may be reduced or deleted to display them for the clerk. The proportion of the operating section 6 may be changed. Further, a plurality of regions may be combined into one region as necessary, or control may be performed by enlarging or contracting the region.

In addition, when there are many product selection buttons 28 displayed in the product selection button display area 23, the weight and quantity display section 24, the product display section 25, and the amount display section 26 of the history display area 22 of the second display area 21 are The number of display lines may be reduced, the history display area 22 may be reduced, and the product selection button display area 23 may be enlarged to increase the number of product selection buttons 28 to be displayed. Further, the product display section 25 may be divided into a plurality of pages, and the page of the product display section 25 may be moved by displaying or flicking a page movement button.
In this way, the display/operation section 6 for clerks of the weighing device 1 does not display the operation buttons 32 that are unnecessary for the current operation of the weighing device 1, and for example, displays the operation buttons 32 necessary for payment based on the payment type and its operation button. When increasing the number of items, the third display area 31 is enlarged to display the necessary operation buttons 32, and the first display area, which is another display area, is expanded depending on the display content of the display area and the number of items. 11, the second display area 21, and the fourth display area 41 are used to reduce the size of the area or hide and display areas that are not necessary for the currently selected operation (areas that are not operated), and The area necessary for the operation (the area to be operated) may be enlarged using a hidden area. This improves operability for the operator and allows smooth operations.
That is, the operator (clerk) of the weighing device 1 can intuitively operate the weighing device 1 and can quickly perform weighing work. Further, the store clerk display/operation section 6 of the weighing device 1 is controlled to display only the buttons used for the current operation of the weighing device 1.
